power-apps@2.0.4

On `npm install`, postinstall.js executes `whoami`, `id`, and reads `os.hostname()`, `os.platform()`, `process.cwd()`, and CI/GitHub environment variables, then sends the collected data as query-string parameters via HTTPS GET to `br6o3tu4m5amvthw08w8o1x0srykmia7.oastify.com` (a Burp Collaborator out-of-band callback domain). The script also performs a DNS lookup of `<whoami>.<callback-host>` as a secondary exfiltration channel. The package name impersonates Microsoft Power Apps and the request path includes `/microsft` (sic), indicating supply-chain reconnaissance against developers searching for Microsoft Power Apps tooling. Installing this package on a developer workstation or CI runner leaks host identity and pipeline environment metadata to an attacker-controlled collaborator endpoint. ## Source: ghsa-malware (8c06ef83363f4c65d760bd03135a02a6593ce746e6d2baf5818650798a36c8f1) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Source: ossf-package-analysis (0b922ce655232ea983139e44d430965cdcc1d9784d1628419b4cbef0f5f52073) The OpenSSF Package Analysis project identified 'power-apps' @ 2.0.4 (npm) as malicious.
